vb示例：

Public Property Name() As String = "Bob"

 等效于

    Private _name As String = "Bob"

    Property Name As String

        Get

            Return _name

        End Get

        Set(value As String)

            _name = value

        End Set

    End Property

c# 示例，在c#中不允许开发者在定义自动属性时，赋值给该属性；不过clr会为属性设定安全的默认值，比如为int赋值0，引用类型赋值null。开发者可以在类的构造函数中为自动属性赋值。

    public class Book

    {

        public string BookName { get; private set; }

        public Book()

        {

            BookName = "c#  自动属性";

        }

    }
